Embodiment
Below in conjunction with accompanying drawing and preferred embodiment technical scheme of the present invention is described in detail.The embodiment that below gives an example only is used for explanation and explains the present invention, and does not constitute the restriction to technical scheme of the present invention.
As shown in Figure 1 is communication sketch map between BSC and the BTS.Wherein the LAPD time slot mainly is responsible for the communication carrying of chain of command signaling between base station controller and the base station.According to the design of present system architecture, the communications protocol of LAPD part will be accomplished between the control maintenance panel CMB of signaling processing plate SPB and BTS through the Digital Trunk Board DTB of BSC.Downstream message (comprising O&M message, signaling and beep-page message) arrives the CMB plate of each frame earlier through this LAPD link, be transmitted to each carrier wave of each pair carrier wave cells D TRU again through the HDLC agreement.
Fig. 2 is the communication sketch map between the main and auxiliary frame of BTS.The O&M signaling of BSC end and traffic signaling are sent to the CMB of mainframe through the LAPD link, are routed to the subsidiary engine frame through the chip that continues on this CMB.
Base station site can complete connection when initialization chip to the continuing of LAPD link, that is the complete connection chip is to the connection of LAPD link one-to-many.For a downlink signaling message, it is to mail to which frame that the LAPD module on the BSC end is distinguished according to the identifier TEIID in the message header of this signaling message, thereby issues corresponding LAPD time slot; Base station connecting module (combining of promptly continue chip and corresponding software) is when receiving this signaling message; Send it to all time slots of this LAPD link connection; So just this downlink signaling message has been handed down to corresponding main and auxiliary frame, main and auxiliary frame sends to each carrier frequency through HDLC again.Because the chip that continues on the CMB only supports one to advance to have more; Do not support that advancing one goes out more, promptly under the situation of LAPD timeslot multiplex, do not support many upstream messages through the LAPD time slot of chip that the continues output that continues; So it is as shown in Figure 3 for the upstream message of each frame; After need being incorporated on the LAPD time slot through the QMC of mainframe CMB, export to the chip that continues, chip is sent to BSC with the upstream message that merges through a LAPD time slot through Abis interface by continuing.
The part port of chip of continuing is as shown in Figure 4 to the situation that continues of BSC and main and auxiliary frame respectively: the iStream17～iStream 20 of the chip that continues connects the input interface (being A_R, B_R, C_R, D_R mouth) of A, B, C, D; These four input interfaces connect BSC, are used to receive the downlink signaling of BSC; OStream17～oStream 20 connects the output interface (being A_X, B_X, C_X, D_X mouth) of A, B, C, D, and these four input interfaces still connect BSC, are used for mainframe and send up signaling to BSC; Similarly, have iStream21～iStream 24 to connect E, F, G, H input interface (being E_R, F_R, G_R, H_R mouth), this four interface connects the subsidiary engine frame, is used to receive the up signaling of sending from the subsidiary engine frame; OStream21～oStream 24 connects E, F, G, H output interface (being E_X, F_X, G_X, H_X mouth), and this four interface still connects the subsidiary engine frame, is used for mainframe and sends downlink signaling to the subsidiary engine frame; Stream26 meets QMC.
Provide base station of the present invention through embodiment below and realize that the main and auxiliary frame of LAPD link inserts the method for configuration, comprises the steps:
Carry out the configuration and the complete connection of LAPD time slot when (1) the main and auxiliary frame of BTS powers on;
At first confirm the LAPD link of a time slot according to machine top dial-up, main and auxiliary frame is connected with BSC on this LAPD time slot through multiplexing mode in the base station site at this moment, promptly accomplishes and initially continues;
After receiving the LAPD link configuration that BSC issues,, then that the LAPD time slot is all multiplexing if the BTS mainframe is judged the LAPD timeslot number of configuration less than the maximum reusable number of LAPD time slot in BTS system M; If judge the LAPD timeslot number that disposes more than or equal to M, then multiplexing M bar LAPD time slot; Again continue according to this then.
At this, the maximum reusable number of LAPD time slot M confirms according to port number and main and auxiliary frame total number that QMC can be provided for multiplexing LAPD time slot in the BTS system.For example, QMC has 32 available ports, and wherein 9 ports are carried frequently; 9 ports are done other use; Remaining 14 ports are provided for multiplexing LAPD time slot, because main and auxiliary frame total number is 3, so a multiplexing LAPD time slot needs 3 QMC ports; So at most can only multiplexing 4 LAPD time slots, i.e. M=14/3=4 (division rounding operation) in the BTS system.
(2) receive the physical logic relation configuration that BSC issues after, the BTS mainframe carries out the configuration and the complete connection of LAPD time slot again according to the carrier frequency quantity of subsidiary engine frame in the configuration;
Suppose the LAPD timeslot number of BTS configuration is made as n, mainframe carrier frequency number is a, and two subsidiary engine frame carrier frequency numbers are respectively b and c, and distribution method is following:
A, when n≤M, the multiplexing n bar of main and auxiliary frame LAPD time slot does not need to continue again;
B, when n＞M, main and auxiliary frame is independently used n bar LAPD time slot (being that the LAPD time slot is not multiplexing), mainframe directly is routed to the subsidiary engine frame through the chip that continues, need be through the QMC of mainframe, and main and auxiliary frame is all carried out two-way continuing; Be respectively main and auxiliary frame and distribute the LAPD time slot, wherein:
The LAPD time slot bar number that is two subsidiary engine frame configurations is respectively: (n * b)/(a+b+c), (n * c)/(a+b+c);
For the LAPD time slot bar number of mainframe configuration is n-(n * b)/(a+b+c)-(n * c)/(a+b+c);
When main and auxiliary frame sum greater than 3, be m for example, m is a positive integer, i.e. mainframe and (m-1) individual subsidiary engine frame, then:
The LAPD time slot bar number that disposes for the subsidiary engine frame is respectively: (n * n2)/(n1+n2+...+nm), (n * n3)/(n1+n2+...+nm) ... (n * nm)/(n1+n2+...+nm);
For the LAPD time slot bar number of mainframe configuration is n-(n * n2)/(n1+n2+...+nm)-(n * n3)/(n1+n2+...+nm)-(n * nm)/(n1+n2+...+nm).
Division in the algorithm of above-mentioned configuration LAPD time slot bar number is rounding operation.
C, calculate according to the signaling requirement of every maximum reusable carrier frequency numbers of LAPD time slot (for example be 6), if the carrier frequency that the LAPD number of time slot can not ample supply subsidiary engine frame, carrier frequency obturation that then will be unnecessary, and report and alarm; Again be configured by B then, if carrier frequency that still can not ample supply subsidiary engine frame then need increase the LAPD time slot through manual work and be configured.
D, when continuing; In order to let the LAPD time slot of same frame be distributed on different E 1 line as far as possible, adopt the method that continues in turn, promptly at first inquire the LAPD time slot of dial-up connection; By the ascending subsidiary engine frame 1 that continues of LAPD time slot, subsidiary engine frame 2; ..., reach the maximum number that continues up to the subsidiary engine frame, with the remaining LAPD time slot mainframe that all continues.
Fig. 5 promptly is the distribution and the connecting method of multiplexing LAPD time slot, multiplexing 4 LAPD time slots at most simultaneously when (M=4) in n≤4.Fig. 4 is example to use a LAPD time slot, can find out that the chip that continues is responsible for continuing of LAPD time slot, and CMB mainly is responsible for configuration continue each passage and the time slot of chip, to send such as business and management information such as BSC LAPD and cascade LAPD.
The Digital ID of the ST back channel number of chip that continues among Fig. 5; The timeslot number of numeral LAPD in its bracket has identified software handshaking procedure in the base station initiated process whereby, and it comprises descending continuing and up continuing; Wherein dotted arrow is descending continuing, and solid arrow is up continuing.
Descending O&M signaling and traffic signaling are inserted by the A interface (or B or C or D interface) of mainframe E1; Be routed to QMC and subsidiary engine frame through the mainframe chip that continues; The exit passageway that correspondence continues number (ST number) and timeslot number fixed configurations, downlink signaling The data broadcast mode sends to QMC and subsidiary engine frame.
Continue for up; Chip does not have to advance one more and go out characteristic owing to continue, so must pass through the QMC processing, just the up signaling of the subsidiary engine frame A mouth by subsidiary engine frame E1 is sent; D mouth input through mainframe E1; And being routed to the QMC of mainframe through the chip that continues of mainframe, this QMC is routed to continue chip with the signaling message that subsidiary engine frame carrier frequency and mainframe carrier frequency send through a LAPD time slot (time slot 5) through storage mode, by the continue A interface of arrival bastion host frame E1 of the chip that continues.
Fig. 6 has identified under the situation of not multiplexing LAPD time slot when n＞4 (M=4), and O&M signaling and traffic signaling are routed to the connecting method of subsidiary engine frame by mainframe, mainly comprise following steps:
(1) carry out the LAPD time slot configuration, the algorithm of the configuration LAPD time slot bar number of introducing according to the front calculates, and calculates the LAPD time slot bar number that main and auxiliary frame is given in configuration respectively;
(2) main and auxiliary frame signaling connecting, it comprises selects the LAPD time slot, carries out up continuing and descending continuing.Select the time slot of different port when selecting the LAPD time slot, this is in order to prevent that an E1 line is unlikely to all service disconnection on the base station when breaking down as far as possible.The employing method is exactly that the wheel flow allocation method method introduced of front is configured.
(3) handshaking procedure is following:
Downlink signaling message is shown in dotted arrow; A mouth by bastion host frame E1 inserts; Directly be routed to the D interface of mainframe E1 through the chip that continues on the mainframe; The D interface of mainframe E1 connects the A interface of subsidiary engine frame E1 through E1, and the chip that continues through the subsidiary engine frame can be routed to subsidiary engine frame QMC, also can the next subsidiary engine frame of line.
Up signaling continues the A interface that chip sends to subsidiary engine frame E1 through the subsidiary engine bridge joint shown in the solid line arrow, the A interface of subsidiary engine frame E1 connects the D interface of mainframe E1, and directly sends to the A interface of mainframe E1 through the chip that continues of mainframe.Can find out the QMC port that need not use mainframe in this case.
